We used to have milk deliveries up until about 1975.
I remember the milkman but we had a metal box outside and would leave a list. He brought milk, butter, ice cream and all that. I’d often check ice cream on the list after my parents put it out so they had to take it. lol
I also remember the postman would take our dogs in his truck around out block. They loved riding with him. It was truly a simpler world and different time.
All the homes in my neighborhood had milk chutes built into the wall. My brother was kinda scrawny and would get calls from neighbors to scramble through the milk chute to unlock the door from inside when they forgot their keys.
